QUESTION: 83 Topic: 1, Access Control

Which of the following choices describe a Challenge-response tokens generation?

A workstation or system that generates a random challenge string that the user enters into the token when prompted along with the proper PIN.
A workstation or system that generates a random login id that the user enters when prompted along with the proper PIN.
A special hardware device that is used to generate ramdom text in a cryptography system.
The authentication mechanism in the workstation or system does not determine if the owner should be authenticated.

Answer(s): A

Explanation:

Challenge-response tokens are:
- A workstation or system generates a random challenge string and the owner enters the string into the token along with the proper PIN.
- The token generates a response that is then entered into the workstation or system.
- The authentication mechanism in the workstation or system then determines if the owner should be authenticated.

QUESTION: 86 Topic: 1, Access Control

In biometrics, the "one-to-one" search used to verify claim to an identity made by a person is considered:

Authentication
Identification
Auditing
Authorization

Answer(s): A

Explanation:

Biometric devices can be use for either IDENTIFICATION or AUTHENTICATION ONE TO ONE is for AUTHENTICATION
This means that you as a user would provide some biometric credential such as your fingerprint. Then they will compare the template that you have provided with the one stored in the Database. If the two are exactly the same that prove that you are who you pretend to be.
ONE TO MANY is for IDENTIFICATION
A good example of this would be within airport. Many airports today have facial recognition cameras, as you walk through the airport it will take a picture of your face and then compare the template (your face) with a database full of templates and see if there is a match between your template and the ones stored in the Database. This is for IDENTIFICATION of a person.
Some additional clarification or comments that might be helpful are: Biometrics establish authentication using specific information and comparing results to expected data. It does not perform well for identification purposes such as scanning for a person's face in a moving crowd for example.
Identification methods could include: username, user ID, account number, PIN, certificate, token, smart card, biometric device or badge.
Auditing is a process of logging or tracking what was done after the identity and authentication process is completed.
Authorization is the rights the subject is given and is performed after the identity is established.
Reference OIG (2007) p148, 167

Crossover Error Rate (CER)
True Rejection Rate (TRR) or Type III Error

Answer(s): A

Explanation:
